Bubble Counter for use in Pressurised or DIY CO2 injection Systems for Hi tech planted aquariums.

This is a sealed unit so no CO2 leakage through corroded rubber seals.

Fill the unit by immersing it in water, connect input to your needle valve and output to your CO2 diffusion system, then count the bubbles per second to know how much CO2 is reaching your aquarium.

I recommend the use of CO2 proof tubing and an anti return valve between regulator and bubble counter.

Why inject CO2 ? In a heavily planted aquarium the biggest limiter of plant growth is available carbon, fish only produce so much CO2, after that is used up plant growth slows dramatically, by injecting CO2 you provide a ready source of carbon for maximum plant growth. CO2 injection is the one thing that has the biggest effect on a planted aquarium.
